500 PM AST MON AUG 17 2009
AN AIR FORCE RECONNAISSANCE AIRCRAFT INVESTIGATED ANA THIS AFTERNOON
AND DID NOT FIND A CLOSED WIND CIRCULATION. CONSEQUENTLY...ANA IS
NO LONGER A TROPICAL CYCLONE AND THIS WILL BE THE LAST ADVISORY ON
THIS SYSTEM UNLESS REGENERATION OCCURS.
THE REMNANTS OF ANA ARE MOVING AT 290/21. THE REMNANT TROUGH IS
EXPECTED TO CONTINUE ON THIS PATH...BRINGING THE THREAT FOR HEAVY
RAINFALL AND GUSTY WINDS TO HISPANIOLA AND CUBA OVER THE NEXT
COUPLE OF DAYS. GFS AND ECMWF SOLUTIONS HAVE BOTH SHIFTED SOUTH
FROM EARLIER...TAKING THE 850 MB VORTICITY CENTER OVER OR EVEN
SOUTH OF CUBA...LIMITING THE CHANCES OF REGENERATION.
FORECAST POSITIONS AND MAX WINDS
INITIAL 17/2100Z 17.5N 68.0W 30 KT
